Effect of object location on the density measurement and hounsfield conversion in a NewTom 3G cone-beam computed tomography unitDownload
Objectives: The purpose of this study was to determine the effect of an object's location in a cone beam CT imaging chamber (CBCT-NewTom 3G) on its apparent density and to develop a linear conversion coefficient for Hounsfield units (HU) to material density (g cm−3) for the NewTom 3G Scanner....
Computers have been used in diagnostic imaging for decades, but High-Performance Computing (HPC) in diagnostic imaging is rather rare because of the high cost associated with traditional HPC. Recent advancements in shared memory computers and the large market for commodity graphic cards have...
High density/high atomic number metallic objects create shading and streaking metal artifacts in the CT image that can cause inaccurate delineation of anatomical structures or inaccurate radiation dose calculation. We developed techniques for reducing metal artifacts in both megavoltage CT...
